Lithium ion Battery Family

Lithium battery family
In the new energy automobile industry chain, lithium battery which is close to 40% has been an important cost of vehicle, . In addition to national policies, the development of lithium-ion battery materials, is currently the top urgent issue for lithium-ion battery production companies and research institutions are willing to carry out the material work.
From the perspective of lithium battery material system, at present lithium batteries include lithium iron phosphate battery (referred to as “battery”) and three cells(using lithium nickel manganese cobalt oxide cathode material for three). These uses range from small mobile communication of lithium batteries, lithium batteries, large distributed storage devices and other lipo battery pack scenery. Among them, the energy density of lithium battery concerns and security requirements; storage batteries for high energy density, long life and economic requirements.

Most of the domestic power battery uses lithium iron phosphate battery pack and tenary, used in new energy cars and buses. Lithium iron phosphate battery safety and also have a greater drop in costs in recent years; three-way batteries as the technology matures, because of its higher energy density, rapid development of applications in the field of new energy cars, is gradually to replace

Some share of lithium iron phosphate battery. In the field of energy, taking into account the maturity of the batteries, economy,
Front is mainly dominated by lithium iron phosphate.
Shanghai Electric Institute of advanced materials application Dr Liao Wenjun, Director of the Research Office of the Shanghai State-owned assets, said Shanghai Electric has been around storage battery research and development work in the area. 2012 start storage lithium battery research and development project, batteries, battery, battery modules and control management system results, mainly used in grid-connected renewable energy and distributed energy storage devices.

In addition, the Central Cooperative Institute with Fudan University of Shanghai Electric, currently developed by lithium titanate battery has obtained initial results through independent research and development of battery materials and electrolyte, effectively inhibit the flatulence of the battery. “For specific applications, each battery systems have advantages and disadvantages, we want to find some market segments. Lithium battery pack life is long, reaching more than 10,000 times, and security and three lithium iron battery, charging and discharging large magnification, but low energy density. “Liao Wenjun said the advantages of lithium-titanate battery, can be applied to electric buses, fast-moving charging stations, lifting machines, distributed storage areas of the port. From cost view, although currently titanium acid lithium battery of initial cost high, titanium acid lithium about 7000-10000 Yuan/each kWh, phosphate iron lithium about 3000 Yuan/each kWh, but from full life cycle of using cost view, still has obviously advantage, and with titanium acid lithium battery market pushed, Shang scale Houlifepo4 battery pack material and battery cost are has larger declined space; on the, storage can battery of hidden economic high, that promote new energy grid zhihou can prevent power fluctuations, improve power quality, This is very favourable for new energy a massive power.

Due to the different energy storage technology course in cost, operation mode, applications have their own advantages and disadvantages. Shanghai outside of lithium-ion batteries for energy storage, electrical Central Institute, and also the development of redox flow battery, Shanghai
